A031200100011 COMMENT -Abstract: Angular Distributions of a A031200100012 6-Li(P,ALPHA)3-He Reaction were Measured at Six Angles A031200100013 For 140 KeV Proton Energy Using Nuclear Track A031200100014 Detectors. The Measurements were Carried Out Over A031200100015 60-160 Lab. Angles in 20 Increments Using a Scattering A031200100016 Chamber of Beam Line of the 350 Kv Accelerator. A031200100017 Semiconductor Silicon Surface Barrier Detector was A031200100018 Placed at +160 Degrees and was Used As a Monitor. The A031200100019 Results have Shown That the Cr-39 Detector has A031200100020 Excellent Capabilities to Distinguish 1.4-2.7 MeV AlphaA031200100021 + 3-He Particles from the Reaction and 8-9.4 MeV A031200100022 Alpha-Particles from the 7-Li(P,A)4-He Reaction ThroughA031200100023 Their Track Diameters. However,It was not Possible to A031200100024 Distinguish Between the 2.3 MeV 3-He Ions and the 1.7 A031200100025 MeV 4-He Ions from the 6-Li(P,A)3-He Reaction from A031200100026 Their Track Diameter Measurements, But It was Possible A031200100027 To Differentiate Between the Two, from the Darker A031200100028 Contrast of the 3-He Particles Caused by Its Deeper A031200100029 Tracks As Compared to Those of 4-He. A031200100030 SAMPLE The Lithium Targets were Prepared by Evaporating 2400 A031200100031 Angstrom Thick Li-F Layers on 1.5 Millimeters Thick A031200100032 Tantalum Sheets.
